Bushings are components of a car's suspension that make it run more quietly.

Silentblocks can be made of polyurethane or rubber and are covered with an iron or aluminum metal edge.

Whether made of rubber or polyurethane, silentblocks absorb the vibrations and noise produced by a car's suspension, and have a major influence on its behavior.

When you hear a noise or squeak coming from your vehicle's suspension, this could indicate that the sinoblocs are damaged and need to be replaced.
